Abstract

Claims (16)

1. A brake hub assembly couplable to the axle of a vehicle, the brake hub assembly comprising:

a brake hub defining a central axis, the hub having a first set of lugs and a second set of lugs axially spaced from the first set of lugs;

a wheel flange plate to which a wheel is securable, the wheel flange plate being removeably coupled to the first set of lugs with a first set of fasteners; and

a brake disk removeably coupled to the second set of lugs with a second set of fasteners;

wherein each of the wheel flange plate and the brake disk is removable from the hub without removing the hub from the axle.

2. The brake hub assembly of claim 1 , wherein at least one of the first set of lugs and the second set of lugs are integrally formed with the hub.

3. The brake hub assembly of claim 1 , wherein the second set of lugs is proximate an inboard end of the brake hub and the first set of lugs is between the second set of lugs and an outboard end of the brake hub.

4. The brake hub assembly of claim 1 , wherein the brake disk defines a slot, and wherein a lug of the second set of lugs is received within and moveable radially along the slot.

5. The brake hub assembly of claim 4 , wherein the brake disk defines a plurality of slots and wherein each lug of the second set of lugs is sized to pass axially through one of the plurality of slots.

6. The brake hub assembly of claim 1 , wherein brake disk is axially slideable over the second set of lugs.

7. The brake hub assembly of claim 6 , wherein the wheel flange plate is fastened to an outboard end of each of the first set of lugs.

8. The brake hub assembly of claim 1 , wherein the wheel flange plate includes a wall along an inner circumference of the plate, and wherein the wall defines a plurality of hub pilots at a first radial distance from the central axis and a plurality of wheel pilots at a second radial distance from the central axis, the second radial distance greater than the first radial distance.

9. The brake hub assembly of claim 1 , further comprising a stopping plate and an axial preload spring each coupled to the hub, and wherein the brake disk is between the axial preload spring and the stopping plate.

10. The brake hub assembly of claim 9 , wherein the axial preload spring biases the brake disk against the stopping plate.

11. The brake hub assembly of claim 9 , wherein the stopping plate is substantially semi-annular in shape.

12. The brake hub assembly of claim 9 , wherein the axial preload spring is substantially “C” shaped.
